Serine346/Serine347 (S346/S347) is major phosphorylation site of the Angiotensin Receptor 1 (AT1). The pS346/pS347-AT1 antibody detects phosphorylation in response to agonists. S346/S347 phosphorylation is likely to be involved in efficient ligand sequestration by AT1.

Figure 1. Agonist-induced Serine346/Serine347 phosphorylation of the Angiotensin Receptor 1. Upper panel, HEK293 cells stably expressing the Angiotensin receptor 1 (AT1) were either not exposed or exposed to 100 nM Angiotensin II for 30 minutes. Cells were lysed and immunoblotted with the anti-pS346/pS347-AT1 antibody (7TM0034C) at a dilution of 1:1000. Lower panel, blot was stripped and reprobed with an phosphorylation-independent anti-AT1 antibody to confirm equal loading of the gel.
